MICI IRIS Microscopic No No

Testing Algorithm

If results from blood, clarity, leukocyte esterase, nitrite, or protein indicate microscopy is necessary, then an automatic microscopic examination will be performed at an additional charge.

A microscopic exam will be performed when the urinalysis with microscopy meets one or more of the following criteria:

-Protein 30 mg/dL or above

-Positive leukocyte esterase

-Positive blood

-Positive nitrite

-Clarity - Not clear (Ex. sl. cloudy, turbid, etc.)

-Dysmorphic red blood cells
